Lol, we all do the same shit!
Zoro fans dissing Sanji, and Sanji fans dissing Zoro, it's just part of the enjoyment of this series!
If Sanji fans didn't exist, Zoro fans would feel really lonely in their Ws and Ls, cause there is no one to stick your middle finger to when the moment of victory happens Lmao
I remember feeling the same when I used to watch soccer/football as in school, I had lot of rival fans, and when I moved to college, no one was watching the sport, so I felt less tension from fans of opposite team, which lead me to not care about the sport any more!
Here the same, Sanji fans need Zoro fans, and Zoro fans need Sanji fans, it's just fun to diss when we can
